An adjustable vacuum and support system (25) for evacuating particulate matter, smoke, excess gasses, and molten metal from a work area during TIG welding and for providing adjustable support to a welding head (12). The vacuum system has a vacuum head (36) and a vacuum nozzle (40). An adjustable mounting bracket arrangement (38) has a first portion fixed to the vacuum head (36) and a second portion securable to the welding head (12). The bracket arrangement (38) establishes pivotal and slidable couplings between the welding head (12) and the vacuum head (36). The vacuum nozzle (40) has a support surface (41) for being rested on a surface of a workpiece (100) to support the vacuum head (36) and the welding head (12). The support surface (41) of the vacuum nozzle (40) can be a base bevel (41) surface at the tip of the nozzle (40). An opposed suction bevel surface (43) can have a nozzle aperture (45) interposed therealong. |
